Code :
  • Code: SC434
  • Description: Potential sensor error 3: Vr C
    Vr > 200V. The residual voltage (Vr), the amount of voltage that remains on the surface of the drum after the QL fires is greater than 200V.
  • Causes: • Potential sensor dirty • Potential sensor defective • Charge roller defective • Charge power pack defective • OPC defective
  • Code: SC435
  • Description: Potential sensor error 4: Vr Y
    Vr > 200V. The residual voltage (Vr), the amount of voltage that remains on the surface of the drum after the QL fires is greater than 200V.
  • Causes: • Potential sensor dirty • Potential sensor defective • Charge roller defective • Charge power pack defective • OPC defective
  • Code: SC436
  • Description: Potential sensor error: Vd K
    The VdHome reading, the first step of the process control self-check, detected that the development potential of the unexposed areas of the drum are not within the prescribed range (-500 to -800)
  • Causes: • Potential sensor dirty • Potential sensor defective • Charge roller defective • Charge power pack defective • OPC defective
  • Code: SC437
  • Description: Potential sensor error: Vd M
    The VdHome reading, the first step of the process control self-check, detected that the development potential of the unexposed areas of the drum are not within the prescribed range (-500 to -800)
  • Causes: • Potential sensor dirty • Potential sensor defective • Charge roller defective • Charge power pack defective • OPC defective
  • Code: SC438
  • Description: Potential sensor error: Vd C
    The VdHome reading, the first step of the process control self-check, detected that the development potential of the unexposed areas of the drum are not within the prescribed range (-500 to -800)
  • Causes: • Potential sensor dirty • Potential sensor defective • Charge roller defective • Charge power pack defective • OPC defective
  • Code: SC439
  • Description: Potential sensor error: Vd Y
    The VdHome reading, the first step of the process control self-check, detected that the development potential of the unexposed areas of the drum are not within the prescribed range (-500 to -800)
  • Causes: • Potential sensor dirty • Potential sensor defective • Charge roller defective • Charge power pack defective • OPC defective
  • Code: SC440
  • Description: Image transfer power pack error: K
    An interrupt checks the status of the power pack every 10 ms. This SC is issued if the VBCU detects a short in the power pack for K, M, C, or Y.
  • Causes: • Transfer belt damaged, insulation damaged • Insulation on high voltage cable damaged • Another hot point inside the machine has damaged insulation • Insulation around high-voltage power supply damaged
  • Code: SC441
  • Description: Image transfer power pack error: M
    An interrupt checks the status of the power pack every 10 ms. This SC is issued if the VBCU detects a short in the power pack for K, M, C, or Y.
  • Causes: • Transfer belt damaged, insulation damaged • Insulation on high voltage cable damaged • Another hot point inside the machine has damaged insulation • Insulation around high-voltage power supply damaged
